I have a SERVO AMPLIFIER BiSVSP equipment, Model A06B-6164-H344, with error on screen "439 overvoltage DC circuit", on the servo display I see the red LED error indicator on and the code 73.
The equipment has an autotransformer at the input, and its voltages are approximately 210VAC, if I disconnect the input and feed the control board with 24VDC the error still appears.
I think that may be damaged the LM339 integrated LM339 that carries the control board but I'm not sure yet, before doing anything I would like to know if anyone has had this error or if you can help me in something.
Greetings to all!
